'TRUSSING-MACHINEL SPEGIFICATIQNforming part of Letters Patent No.699,121, dated April 29, 1902.

v Application filed October 28, 1901. Serial No. 80 305. (EomodelJ Toall whomz't may concern:

Be it known that I, LOUIsD. VOGEL, a citi- Zen of the United States,residing atOrnaha, in the county of Douglas" and State of Nebraska, haveinvented anew and useful Truss ing-Machine,of which the following is aspecification.

My invention is an improved trussing-ma chine for use in the manufactureof tubs and other similar, articles; and it consists in the peculiarwconstruction-and corhbination of devices hereinafter fully set forthandclaimed.

In the accompanying drawings, Figure 1 is a side elevation of atrussing-machine embodying my improvements. Fig. 2 is partly a frontelevation of the same and partly a' vertical sectional view taken on aplane at right angles to that of Fig. 1. Fig. 3 is a top plan view ofthe same, -partly in section one. plane below the plunger and abovetheforms on the form-carrier. Fig.4 is a vertical longitudinal centralsectienal view of the same, taken on a plane at right angles to that "ofFig. 2. Figs. 5 and. 6 are detail sectional views of one of theexpansibleplungers.

On opposite sides of a'ba'sel are a pair of vertical brackets2,iwhichsupports -p1ate 3,;

that bears on theirluppe'r sidesl' Braees. rare secured to the innersides of thesaidbrackets and to the upper s'ide'of the'base 1.- 'fThesaid brackets are provided with bearings for' a shaft 6 and for apower-shaft}, which is disposed to one side of theshaft 6L Thez lat terhas spur-wheels 8 secured on its ends, and

the powe :shaft has pinions 9, which engage said spur-wheels? A circularrevoluble table 12,which carries a plurality of trussing-forms 13, ismounted on the upper end of a shaft 14, which revolves, in bearings inthe base 1 and in theplateY The trussing-forms are disposed equidistautapart; and thetab1e'12'is' previded in its peripherywith stop-notches16, which correspond in number with the trussin'g-form's and aredisposed inline radiallywith the centers thereof. A's'top 17 is..provided to engage the stop-notches "successively to arrest "the"rota- "tion of the table and lock the same in position, and the saidstop is provided with a suitable pedal 18. As here shown, the upperportion of the stop projects through and operates in a slotted opening-19, with which the plate?) is provided .on its rear side. It will beobserved by reference to Figs. 1 and 3 of :the drawings that'ftherevoluble table 12 extends beyond the front side of the plate 3.

. Two pairs of vertically-disposed parallel guide-rods 2O hav'e'theirlower portions disposedand securedin openings in the sides of the base1' and plate 3. The, said guide-rods extend upwardly above the table 12a suit- ,able distance, and their upper ends are connected together wecross plate or beam 21. The'satne is'secured to the upper end of theguide-rod byn'uts 22 and is provided at its ceu'terwith a verticalbearing 23, above which 'is' an oil-cup 24. "{Slide-yokes 25 operatevertically on the respective pairs of guide-rods 20, and'a crosshead 26is operated by the said slide-yoke's. Thelatter are provided on theirouter. sides with trunnions 27. The gear-wheels 8 have crank-pins 28,which are radially adjustable ;therein, and pitmen 29 connect the saidtrunnions of the slide-yokes toTthe said crank-piiisof the gear-wheels8. In the form of my invention here shown each pitrnan is composed. of.a pair of heads 30, which areresp'ectively clamped on and form.bearingsfor one of the trunnions 27 and one of the crank-pins 2 8,androds 31, which connect the said heads together. I The-sections of therespective heads of the pitm'en are clamped together by'nuts 32,whichare-screwed on the i newt Itwill he understoodfrom the foregoing thatwhen the shaft 6 is in rotation reciprocating verticalmovement willbezimparted to the cross-head 26. The endsof the latter engage notch es.3 3 ,in the innerisidesof the slideyokes. The'said notchesare of greatervertical extentthan the thickness of the. ends of the said cross-head,and thereby lostmotion is provided between the cross head and theslide-yokes; the latter at each limit. of :their stroke moving a slightdistance independently of the cross-head while the crank-pins 28ampassing the dead-centers of thewheels 8.

A vertically-disposed.plunger 'rod 34operates in the bearing-23 of thecross-plate 21 and passes through a central opening in the cross-head26. The said plunger-rod has a collar 35 at a suitable distance from itslower end, which collar is adapted to be engaged by the upper side ofthe cross-head on the upstrokes of the latter, so that said plunger-rodwill be raised by the said cross-head when the latter is movingupwardly. A cap-plate 36 is secured under the central portion of thecross-head by bolts 37. Cushions 38, which may be made of rubber orother suitable material, are interposed between the cross-head and thecap-plate, so that the latter is yieldably connected to the former, andthe said cap-plate is provided on its lower side with an annular flange39 of suitable diameter, the inner side of which is inclined upwardlyinwardly, as at 40. The diameter of the capplate within its flange 39corresponds with the exterior diameter of the upper edge of the tubs orother articles to be trussed by the machine. On the lower portion of theplunger-rod are apair of plunger-heads 41 42, the latter being lowermostand of less diameter than the former. The said plunger-heads are asuitable distance apart and are free to play vertically on theplunger-rod. The latter has a stop-collar 43 to limit the downward playof the plunger-head 41 and a stop-collar 44 to limit the downwardmovement of the plunger-head 42. It will be understood that theplunger-heads will be of suitable size to enable them to enter a tub orother article in one of the forms 13 on the downstroke of thecross-head.

Prior to setting the machine in motion to cause the cross-head todescend the table 12 will be locked in position to dispose a tub orother article in one of the forms 13 in position directly under theplunger-rod and the plunger-heads carried thereby. On the downstroke ofthe cross-head the plunger-heads enter the said tub or other article,expand the staves thereof within the hoops or rings of the tub,and movethe staves downwardly to tighten the hoops or rings thereon. As theplunger-heads descend initially in the tub their descent is arrested bytheir engagement with the inner sides of the staves thereof, and thecross-head continuing to descend the flange 39 of the cap-plate 36 ridesover the upper ends of the staves, the beveled inner side of said flangedrawing the upper ends of said staves inwardly, evening the same andpreventing the staves from splitting. Said cap-plate as it completes itsdescent with the cross-head levels the upper ends of the staves, as willbe understood. Owing to the lost motion which is provided between thecrosshead and the slide-yokes the cap-plate is caused to dwell on theupper side of the tub for an instant prior to the ensuing ascent of thecross-head.

I provide a vertically-movable arm 45 to release the plunger-heads andraise them in the trussed tub prior to the ascent of the crosshead. Thisplunger-arm is operated by an eccentric 46, which is fast on the shaft6.

The plunger-heads are expansible radially,

being provided with radially-movable members 47, which are pressedoutwardly by springs 48. This construction of the plunger-heads enablesthem to be raised and released from the trussed tub by the upwardmovement of the arm 45.

The revoluble table 12 has a gear 49 on its lower side, which is engagedby a pinion 50 on a shaft 51. A sprocket-wheel 52 on said shaft 51 isconnected by an endless sprocketchain 53 to a sprocket-wheel 54 on ashaft 55, that is also provided with a sprocket-wheel 56. Said wheel 56is connected by an endless sprocketchain 57 to a sprocket-wheel 58,which is loose on the shaft7 and has a clutch member 59. A power-pulley60, driven by a suitable belt from a counter-shaft, isloose and capableof longitudinal motion on the shaft 7 and provided with a clutch member59 to engage said clutch member59, and thereby impart rotary motion tothe wheel 58, and hence to the table 12. Said sleeve has at its oppositeside a clutch member 61, adapted, in coaction with a clutch member 61 onsaid shaft '7, to impart rotary motion to the latter, and hence to theshaft 6, when said sleeve is unclutched from the said sprocket-wheel 58.Hence rotary motion may be alternately imparted to the table and to theshaft 6, the latter, as before described, operating the plunger-headswhen the table is at rest. An arm 62, which is connected to said sleeveand to the arm 18, automatically shifts the powerpulley into engagementwith the wheel 58 to rotate the table 12 when the stop 17 is disengagedfrom the latter and reversely shifts said power-pulley into engagementwith the shaft 7 when said step is in looking engage ment with the saidtable.

Having thus described my invention, I claim- 1. In a trussing-machine,the combination with a relatively fixed form and hoop-support, of areciprocating element movable to and from the form, a plunger to enterthe form and radially expand the staves of the Work, said plunger beingmovable with and independently of the reciprocating element, and meansto release the plunger from the interiorof the work, prior to therecessional movement of the reciprocating element, substantially asdescribed.
